WATER OR STEAM BOILER.

SPECIFICATION forming part of Letters Patent No. 469,152, dated February16, 1892.

Application filed September 2, 1891. Serial No. 404,564. (No model.)Patented in Switzerland April 6, 1891] N0. 3,427, and i Italy June30,1891,LVIIL155.

To all whom it may concern:

Be it known that I, ERNST KoRTING, a subject of the King of Prussia, andresiding at Hanover, Kingdom of Prussia, Germany, have invented new anduseful Improvements in Vater or Steam Boilers, (for which I haveobtained patents in Switzerland April 6, 1891, No. 3,427, and in ItalyJune 30,1891, No. 155, Vol. LVIIL) of which the following is aspecification. 7

My invention consists in a water or steam boiler formed of hollowcast-iron sections or vessels, which are flat or substantially fiat andprovided with an internal opening and vertical cylinders at eitherextremity, so that when the said sections are arranged one above theother and the flanges of the cylinders or upright tubes are tightlyconnected together the internal opening will form a vertical fire-placeto receive the fuel, and the said cylinders or tubes will form acontinued pipe, permitting the circulation of the water and the escapeof the steam from the different parts of the above-mentioned sections orvessels. Owing to the flanges of the upright tubes, the vessels orsections will not bear closely upon each other, so that there are slotsbetween the several vessels or sections, which allow the direct supplyof air from the outside to the fuel in the fire-place and the escape ofthe products 'of combustion into the flue.

In the annexed drawings, Figure 1 is an elevation of aboiler constructedaccording to my invention, partly in section. Fig. 2 is a sectionalelevation at a right angle. Fig. 3 is a cross-section through one of thehollow sections or vessels.

a a are the sections, which are shown in Fig. 3 as oval rings withinternal openings 0, forming in the superposed position of the sectionsthe fire-place. The sections a have at either extremity a short uprighttube or vertical cylinder I), provided with flanges by which thearrowsin Fig. l. The slots d, provided on the front part and also on thepartdirected toward the flue between the sections or vessels of theboiler, allow the air to enter from the outside into the fire-place,which, hav1ng passed the fuel in the fire-place, Wlll. pass through theopposite slots d and carry t he products of combustion into the flue.lhe shape of the sections or vessels can be varied. In order, however,to prevent undue pressure, it ispreferable to make the same round oroval.

hen the boiler is required to be used ,for the purpose of generatingsteam,1t 1s advisable to give the separate sections or vesse ls aninclined position, as shown 1n Fig. 1,1n order that the steam as it isgenerated may readily escape and to arrange above the top Vessel a Waterseparator or vessel W, Figs. 1 and 2, similar to those used withwater-tube boilers, which upper vessel can be sub ected, either partlyor completely, to the action of the fire or of the products of combuston.

The shape or form of the hollow sections or vessels a in verticalcross-section may vary, although the design illustrated in thedra wlngs,in which the top and bottom faces incline toward the internal openingCt. e, the fireplace-is to be preferred, as in this form the deposit offuel in the spaces or slots (1 and d between the vessels at is avoided.

In order to secure the greatest possible amount of useful effect fromthe fuel and from the products of combustion, the separate sections orvessels at of the boiler can be provided with a second hollowring-shaped part a, communicating with the vessel a and being of such ashape that the said parts a when in superposed position will bearclosely upon another, forming a channel-shaped fine 0 for conducting thefiregases to the chimney. Moreover, the surface in contact with the firemay, according to any of the well-known methods, be enlarged by makingthe same c orrugated or by forming ribs thereon. lhe

regulation of heat in such a boiler is effected 5 within certain limitsby arranging on the outside of the sections a in the front, or, betterstill, at the back of the same, dampers s s fitting as tightly aspossible, so that by raising or lowering the same a larger or smallernum- IOO ber of the said sections are shut against the entranceof theair or the flow of 'the gases of combustion.

WVhat I claim, and desire to secure by Letters Patent in the UnitedStates, is-

1. A boiler composed of hollow ring-shaped sections arranged oneabove'the other'and at tached to each other by means of flangedcylindrical connecting-pieces open at both ends and having air-supplyslots between the seciions at the front and slots for the escape of theproducts of combustion at the rear, substantially as described.

2. In combination with the hollow 1-ing-' shaped sections arranged oneabove the other and attached to each other by means of flanged cyli-ndrical con necting=pieces open at both endsand having slots at thefrontand at the rear, the hollow ring-shaped parts a, which in the superposedposition of the sections form the flue, substantially as described.

3. In combination with the boiler composed of hollow ring-shapedsections arranged one above the other and attached to each other bymeans of flanged cylindrical connectingpieces open at both ends andhaving slots at the front and at the rear, and the dampers s s,substantially .as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

ERNST KoRTINe.
